Which of the following is an in situ conservation method ?

The correct answer is Sacred Groves.

In‑situ conservation means protecting species while they remain in their natural habitats, preserving the ecosystem in which they evolved.

Sacred groves are areas of forest or natural vegetation that local communities safeguard because of cultural, religious, or spiritual importance. These groves are left largely untouched, allowing native plants and animals to continue living in their original environment.

Other options—wildlife safari parks, botanical gardens, and seed banks—are examples of ex‑situ conservation. Safari parks and botanical gardens keep species in managed or artificial settings, and seed banks store genetic material in storage facilities away from the wild.

Therefore, among the listed choices, sacred groves are the only method that constitutes in‑situ conservation.
